ABSTRACT:
A volatile component is recovered from an inert gas blanketed gas source containing the volatile component, an inert carrier gas, water vapor and oxygen as an impurity by a continuous process including the steps of adsorbing the water vapor from the stream, condensing substantially all of the volatile component from the stream, heating the water vapor-free and volatile component-free gas stream, purging the adsorbers with the heated gas stream and venting the purge gas and desorbed moisture. Inert gas depleted from the source is replenished with oxygen-free inert gas, thereby minimizing the concentration of oxygen in the source.
